A Tethered Balloon Cloud Microphysical and Chemical Sounding System

9504551由这笔赠款支持的鲍里斯研究由北极系统科学全球变化研究计划赞助，并由海洋科学部和极地方案办公室联合赞助。将开展的工作代表着实施名为SHEBA的五年重大研究项目的初步步骤：(1)开发、测试和实施北极海洋-大气-冰过程模式，利用全球环流模式明显改进对当今北极气候包括其变异性的模拟；(2)改进对北极卫星遥感数据的解释，用于北极气候系统的分析，并为模型投入、模型验证和气候监测提供可靠数据。这项工作是内华达大学甜点研究所和阿拉斯加大学地球物理研究所的合作成果。Sheba野外计划期间的几项关键大气测量将使用系留气球进行，这些气球将携带科学仪器，最高可达冰面上方一公里。其中一些仪器必须根据北极的条件进行改装和测试。一组测量集中在云层微植物上，另一组涉及辐射热流测量。当气球在云层中垂直移动时，微物理仪器将提供不同高度的云颗粒的特征。辐射仪器包将包括自平向上和向下的短波通量辐射计、云液态水仪器以及压力、温度、湿度和风的气象包。协作工作将提供通用的操作和数据记录组件。该部也在提供部分支持。能源部。

9504551 Borys Research supported by this grant is under the auspices of the Arctic Systems Sciences (ARCSS) Global Change Research Program and is jointly sponsored by the Division of Ocean Sciences and the Office of Polar Programs. Work to be performed represents preliminary steps towards a major 5-year research project named SHEBA are: (1) to develop, test and implement models of arctic ocean-atmosphere-ice processes that demonstrably improve simulations of the present day arctic climate, including its variability, using General Circulation Models (GCMs), and (2) to improve the interpretation of satellite remote sensing data in the Arctic for analysis of the arctic climate system and provide reliable data for model input, model validation and climate monitoring. This work is a collaborative effort between the University of Nevada, Dessert Research Institute and the University of Alaska, Geophysical Institute. Several key atmospheric measurements during the SHEBA field program will be made from tethered balloons that will carry scientific instruments up to a kilometer above the ice surface. Some of these instruments must be adapted and tested for Arctic conditions. One group of measurements focus on cloud microphytsics and another group involve radiative heat fluz measurements. The microphysics instruments will provide characterizations of cloud particles at different altitudes as the balloon moves vertically through cloud layers. The radiative instrument package will consist of self-leveling up- and down- short-wave flux radiometers, cloud liquid water instruments, and meteorological packages for pressure, temperature, humidity, and wind. The collaborative effort will provide common operational and data logging components. Partial support is also being provided by Dept. of Energy.
